Flood Mitigation Program Whether it’s caused by a hurricane, a Nor’easter, or even heavy rain, flooding is a year-round threat in Delaware. Just a few inches of rainfall can cause immeasurable damage to homes and businesses.

• Delaware Floodplain Ordinance Model (Version 1.8) Delaware’s Flood Damage Reduction Ordinance was created as a guideline for community officials. This document can be used as a stand-alone floodplain ordinance that meets and exceeds FEMA’s National Flood Insurance Program minimum requirements. It is not mandatory that the community adopt this ordinance, but it may be used to strengthen a community’s existing regulations. The ordinance also regulates the Special Flood Hazard Area in a way that reduces risk to property owners. Please contact the State Floodplain Coordinator at the Delaware Department of Natural Resources and Environmental Control at 302-739-9921 if you have any questions.
